RAILWAY-RAIL.

' SPECIFICATION forming part of Letters Patent No. 466,612, datedJanuary 5, 1892. Application filed June 15, 1891. Serial No. 396,245].(No model.)

To all whom it'mcty concern:

Be it known that 1, WILLIAM H. MATTSON, a citizen of the United States,and a resident of Philadelphia, Pennsylvania, have invented certainImprovements in Railwaydtails, of which the following is aspecification.

The object of my invention is to construct an improved railway-rail thatwill be light and substantial and that can be readily and securelyfastened to the chairs.

In the accompanying drawings, Figure l is a sectional view of inyimproved rail. Fig. 2 is a side view looking in the direction of thearrow, Fig. 1. Fig. 3 is a perspective view. Fig. 4 is a sectional viewof the rail, showing its application to a chair. Fig. 5 is a perspectiveview of my rail, illustrating a diliferent form of tread.

My improved rail is what is termed a girder-rail, having a body portionA and a head portion B. This head portion B can be of any formdesired-as, for instance, it maybe made as shown in Fig. 1 or as showninFig. 5. The body portion A is preferably as thin as possible, dependingupon the use to which the rail is p11t,'and has two vertical portions 0and d in line with each other, and between these two portions 0 and d isa longitudinal groove a, extending the full length of the rail, and onthe opposite side of the portion A, directly opposite the groove 0,, isa rib I), also extending the full length of the rail.

Thus the chair can be clamped to the rail at any point, and the chairwhen clamped will have a firm bearing in the groove at one side and afirm bearing directly above and below the groove on the opposite side,forming what may be termed a three-point fastening. While this fasteningholds the rail rigidly in respect to longitudinal or lateral motion, italso looks the rail as regards any vertical motion. This peculiar formof the body of the rail adds greatly to its strength and rigidityWithout increasing its weight or cost, as the rib and groove are formedduring the rolling of the rail.

I dispense entirely with the ordinary baseflange.

I claim as my invention A railway-rail having a head portion and a bodyportion depending from said head portion, said body having verticalportions 0 and d in line with each other, and longitudinally grooved onone side andlongitudinally ribbed on the opposite side, the said rib andgroove extending the full length of the rail, substantially asdescribed.

I11 testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
